Baltimore & Ohio Railroad, Parkersburg Bridge, Ohio River, Parkersburg, Wood County, WV
Significance: Completed in 1871, the Parkersburg Bridge was an important early work of Jacob Linville and incorporated several of his patented innovations. The original channel spans (approximately 348 feet) were of wrought iron and marked the beginnings of an era of long-span trusses. They were fabricated and erected by the Keystone Bridge Company, a firm begun by Andrew Carnegie to provide a market for the output of his famous Lucy Furnace. The remaining spans were principally Bollman trusses of an older type.
